RADIATOR Application filed December 15, 1927. Serial No. 240,193.

This invention relates to an improvement in radiators for heatingpurposes, and has for its object to provide an article of this characterparticularly adapted for built in construction, that is, the radiator towhich my improvement relates is particularly adapted to be placed in awall depression thus conserving the space customarily occupied by theconventional type of radiator.

The primary object of my invention is to provide a radiator of thecharacter mentioned which shall be built up of a number of separatesections which may be connected in various ways to accommodate theinstallation. In other words, my improved radiator maybe widened by theaddition of as many sections as may be required and it may be lengthenedby coupling together a plurality of units. A feature of my inventionresides in the fact that the means for joining the sections and couplingthe units are so located and positioned that none of these parts extendoutside of theplane of the connected sections. The radiator thusproduced is extremely neat in appearance and through other features inits construction, extremely effective for heating purposes.Additionally, it has no projecting or protruding parts so that it may beconveniently placed in a wall opening of any depth without having anyunsightly protruding pipes, valves or other parts.

With these objects and such other objects as may hereinafter appear, inview, I have devised the particular arrangement of parts hereinafter setforth and more specifically pointed out in the claims appended hereto.

Reference is to be had to the accompanying drawing in which Figure l isa front elevation of one of the primary or main sections of my radiator;

' Figure 10 is a front elevation of the heat outlet located above and infront of the radiator; and

Figure 11 is a longitudinal sectional view through the joined unitsdisclosed in Figure 6, said sectional view being taken through theheaders at the lower end of said figure.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

In the embodiment of my invention disclosed in the accompanying drawing,1 indicates one of the, outer or main sections of my improved radiatorand 2 indicates an intermediate section which is generally placedbetween two of the sections disclosed at 1. The section 2 may however,as will be hereinafter described, be coupled merely to one of thesections 1, this being dependent upon the width of the wall depressionin which the radiator is to be installed. The section 1 may be cast in asingle piece or it may be made of sheet metal. Regardless of by whichmethod it is made, it consists of an u per, longitudinally extendingpipe or hea er 3 and a somewhat similarly shaped pipe or lower header 4.It will be understoodthat these two headers project longitudinally ofthe construction and the same are connected by a plurality of integrallyformed pipes or tubes 5. These tubes 5 are preferably provided with aplurality of ribs 6 to afford considerable heating surface andthe pipes5 are spaced by slots or openings 7. The upper header 3 has a projectingend 8 which extends out beyond the end of the outermost tube at theright of the structure disclosed in Figure 1. This end 8 terminates in aboss 9 which is provided with a connection opening 10.

It will be seen that the opening is thus located in one side of theheader 3 and faces inwardly when the structure is viewed from the frontas in Figure 1. The lower header 4 is provided with a rojecting end 11which extends out beyond the end of the outermost tube 5 at the left endof the section 1. This projecting end 11 is provided with a boss 12 andalso has an opening 13 in itsinner side for connection purposes.

It will thus be seen from the construction described that each of theheaders 3 and 4 is provided with an extended or projecting end which hasa connection opening, the two projecting ends just describedbeing-located diagonally opposite to open another in the section. Itwill be also noted that the header 3 has at its end located opposite tothe projection 8 a boss 14 provided with a continuous opening 15extending completely through the header. The diagonally opposite end ofthe section is provided with a similar boss 16 and a connection opening17 extending completely through the boss and open at both sides. It willalso be seen from Figure 3 that the upper header 3 has an opening 18located adjacent to the opening 10 and diagonally opposite in the header4 is located a smaller opening 19 ad'acent to the opening 13 in theprojecting en 11. p v

In Figure 2 is disclosed an intermediate radiator section 2 which isintended to be coupled with one or more sections similar to 1. Thesection 2 is provided with an upper header 20 and a similar lower header21, these headers being connected by the tubes 5 previously describedwith respect to the section 1. The ends of the headers 20 and 21terminate in bosses 22, 23, 24 and 25, these bosses being perforated forconnection purposes as will be ex lained hereinafter.

By reference to igures 6, 7 and 8, the peculiar shape of the lower endsof the headers 3, 4, 20 and 21 will be noted. It will be here seen thatthe headers 3 and 4 are sharply inclined on their faces 26 and lesssharply inclined on their outer faces 27. The headers 20 and 21 on theintermediate radiator sections 2 may if desired, have their opposingfaces 27 uniformly inclined.

It will be seen from Figure 7 that when a series of radiator sectionsare connected together, the lower terminations of the headers will havefaces which converge, creating a desired flue effect and producing theheat effectiveness of the device.

The manner in which a plurality of radiator sections may be coupledtogether is clearly disclosed in Figures 6, 7, 8 and 9. Here it will beseen that there is an outer section, and a similar inner section, thetwosections just mentioned being reversed with respect to one anotherand an intermediate section 2 is connected between them. This connectionis established as follows. The boss 12 located on the projecting end 11is connected to an inlet pipe 28, the opening 19 in the section 1 isconnected to the opening 24 by means of a coupling nipple 29, a packing30 being used in the joint between the meeting parts. The opening 15 inthe section 1 is connected to the opening 23 b means of a couplingnipple 31, the outer si e of said opening 15, being closed by a closureplug'32'; The opening 10 in the projecting end 8 is connected to theopening 13 in the end 11 of the reversed .back

- section 1 on the adjacent unit. The opening 17 in the front section 1is connected to the opening 25 in the intermediate section, the outerside of this opening being closed by a closure plug 34.

The reversed back section 1 clearly disclosed in Figures 6 and 8 is soarranged that its end 9 is located at the bottom of the installationrather than at the top as is the case with the outer section and its end11 is located at the top rather than at the bottom as is found in theouter section 1.

Through thev arrangement disclosed, it will I be seen that when a seriesof units are placed together, the boss 9 will overlap and align with aprojecting end 11 on the adjacent unit, the' aligned parts justmentioned being connected together by a nipple 39. This lining togetherof the units occurs at the top and bottom of each pair of units with theresult that a secure and rigid connection is afforded. It will also beseen that in theassembly herein described wherein a pair of outersections 1 are used with an intermediate section between them, astaggered arrangement of the vertical tubes or pipes 5 is had. In otherwords, the tubes or vertical pipes5 on the intermediate sections 2 areso located that the same lie in registration with the spaces 7 locatedbetween the tubes 5 on the outer sections 1. Thus, the tubes on thethree connected sections are evenly spaced with respect to one anotherproviding an even heating distribution.

It will be seen from the construction described that the radiator unitsherein mentionedmay be assembled in various ways to increase the widthof the radiator and the various units formed of a plurality of sectionsmay be readily coupled together to provide a radiator of any desiredlength. It will zvith its installation in a wall space provided or it.

Referring to Figure 9, it will be seen that the radiator is installed ina wall opening 40 which preferably has a metal lining or casing 41extending behind the radiator. Said casing is also provided with a frontprotecting portion 42. The inner part of the wall is cut away as at 43below the radiator and is provided with an upper opening 44 that iscovered by a grille 45. A closure arrangement of said grille is shown inthe form of a plate 46 which has its upper end pivoted as at 47 andwhich is provided with a lower section 48. The two sections 46 and 48are pivoted together by a longitudinally extending pivot 49 and thelower end of the plate 48 is provided with a projecting knob 50 thatfolds the two parts 46 and 48 relative to one another by verticalmovement within a slot 51 provided in the grille.

Adjacent to the slot 51 are provided a series of spaced stops 52 onwhich a disk 53 provided on' the knob 50 may rest to maintain theclosure plates 46 and 48 in various positions of adjustment The radiatormay be supported in the wall opening 44 in any desired way. It may besupported upon its inlet pipe 28 and its outlet pipe 54 or a furthersupport for it may be had in the form of brackets 55 secured in the wallspace and extending between the vertical pipes 5 and under the upperheaders 3 and 20.

From the foregoing, it will be seen that the various sections of myimproved radiator are such that the same may be assembled in many waysto provide a radiator of any desired thickness and length. Highlyeffective heating is secured with my improved radiator through the useof the inclined lower terminals on the headers which increase the draftentering through the opening 43, forcing the warm air out through thegrille 45 into the room.

Having described one embodiment of my invention, it is obvious that thesame is not to be restricted thereto, but is broad enough to cover allstructures coming within the scope of the annexed claims.

What I claim is 2-- 1. A radiator having front section provided with aplurality of spaced headers, a series of spaced tubes connecting theheaders, a similarly formed back section, and an intermediate sectionlocated between and connected to the front and back sections, saidintermediate section being provided with tubes that are located inalignment with the spaces between the tubes in the front and backsections.

2. A radiator having a main section provided with a pair of parallelconnection openings near two of its diagonally opposite ends, oneopening of each pair being adapted to be connected to another radiatorsection to laterally connect said main section to said other section,the remaining opening of each pair serving to connect to a similarradiator unit by connection means extending transversely of the radiatorsection.

3. A radiator assembly composed of a plurality of connected radiatorunits, each of said units being provided with extended projecting partshaving connection openings whereby a series of units placed togetherwill cause an overlapping of said extended parts and an alignment of theconnection openings therein, nipples extending into and connecting thealigned openings, whereby a plurality of radiator units are joinedthereby, the extended overlapping parts and connections therefor beinglocated within the plane of the units.

4. A radiator section composed of a pair of spaced headers, tubesconnecting the same, one end of each header projecting out beyond thelast tube in the sectlon whereby said projecting ends are locateddiagonally opposite to one another, each of said ends having a pair ofparallel connection openings, the mouth of said openings being in thesame plane as the body of the radiator section, one of said openings ofeach pair being adapted for connection to a similar opening in anotherradiator section and the other opening of each pair receiving aconnection nipple extending transversely of the radiator section.
